DESCRIPTION

The B5S162862 is an advanced high-speed
CMOS 20-BIT TWO PORT BUS SWITCH
fabricated with s ub-micron s ilico n gate and
double-layer metal wiring C

2

MOS tecnology.

It is ideal for 4V to 5.5V V

CC

operations and
ultra-low power and low noise applications,
typically notebook and docking station.
Any nG

output control governs four 5-bit BUS

SWITCHES. Output Enable inputs (nG

)tied

together gives full 20-bit operations. When nG

is

LOW, the switches are on. When nG

is HIGH, the
switches are in high impedance state.
It has ultra high-speed perform anc e at 5V near
zero delay with low O N resist anc e and include
25Ω series resistor to reduce noise resulting from
reflections, thus eliminating the need for an
external terminating resistor.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
